Nani at the double to slay City

Nani's injury-time goal settled a truly wonderful Community Shield as Manchester United roared back from two goals down to beat Manchester City 3-2.

The Portugal winger had already netted with a jaw-dropping leveller in what turned out to be the highest-scoring of these encounters since 1992.

He then capitalised on Vincent Kompany's blunder to win a game that seemed to be City's for the taking after Joleon Lescott and Edin Dzeko had taken advantage of David de Gea's hesitancy.

But Sir Alex Ferguson's introduction of three younger members of his squad at the break triggered one of those comebacks for which United are so famed, Chris Smalling setting the ball rolling six minutes after the restart, triggering a richly-deserved victory charge for the Premier League champions.

The pity was it took a blunder to win it, Vincent Kompany failing to read Wayne Rooney's clearing punt, allowing Nani to rob him and charge forward, rounding Joe Hart before tapping home.
